Continuation of application Serial No. 1229 22, filed October 20, 1902. This application filed July 22,1904.- Serial No. 217,649.

To all whom, it may concern.-

Be it known that 1, CHARLES M. TAYLOR, Jr. a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Suction Apparatus for Dairy Products, of which the following is a specification.

The object of the present invention is to provide neat, compact, cleanly, and efficientmeans for separating the unbroken fatty globules with or without adherent casein from the free milky portions by the application of pneumatics and without fermentation or agitation.

To this and other ends, hereinafter set forth, the invention comprises the improvements to be presently described and finally claimed.

The nature, characteristic features, and scope of the invention will be more fully understood from the following description, takenin connection with the annexed drawings, forming part hereof,and in which there is illustrated, principally in central section, an apparatus embodying features of the invention.

In the drawing, 1 is a cream-chamber, and 2 is a second or vacuum chamber. A housing 3 incloses these chambers, and it is shown as mounted upon legs or supports 4. The base of the housing is shown to slope toward a discharge-opening 5, provided with a suitable closure 6. The vacuum or second chamber 2 is provided with a connection, as 7, by means of which air is exhausted from it by connecting it with any suitable device adapted to exhaust air.

a is a lid or cover fitted to the top of the cream-chamber in such a way as to prevent the access of air.

The exclusion of the outer air to a substantial degree is desirable, because in a place where dairy products abound the air is always more or less infected with bacteria, which induce or promote fermentation, and the exclusion of air secures greater certainty in the product and a greater degree of uniformity in its condition.

The cream-chamber and the second chamber are separated by a detachable and removable perforated or reticulated plate 8.

9 designates transversely-ranging rods or carriers which support the plate 8.

Super-posed upon the plate 8 is a layer of material 10, permeable by the fluid constitu- I cuts of the cream and im permeable by the fatty constituents thereof. An example of such a material is blotting-paper or layers thereof.

It is obvious that with the exception of part 10 the whole apparatus may be made of metal, and therefore readily cleaned.

In use cream is placed in the compartment 1 and the air-pressure in the chamber 2 is made lower than the air-pressure in the compartment 1. Under these conditions the material 10, being impermeable by the fatty constituents, retains them upon its upper surface, while the fluid constituents permeate it, and the effect of the relative difference in air-pressure between the chambers facilitates the removal of the fluid constituents from the under face of the layer 10, so that they fall from it into the chamber 2 and may be subsequently withdrawn by aid of the outlet 5. The fatty constituents are collected from the upper surface of the sheet 10 for use. In this way the described action of the sheet 10 is promoted and the separation is made with comparative rapidity and without opportunity for fermentation and under conditions free from agitation.

It will be obvious to those skilled in the art to which my invention appertains that modifications may be made in details without departing from the spirit thereof. Hence the invention is not limited further than the prior state of the art may require; but,

Having thus described the nature and objects of my invention, what 1 claim as new, and desire to secure by Letters Patent, is-

1. Apparatus for making dairy products comprising a housing provided with acreamchamber and a vacuum-chamber, a perforated support interposed between the two, and a layer of material carried by said perforated support and permeable by the watery and impermeable by the fatty constituents of cream, substantially as described.

2. Means for making a dairy product comprisinga housing provided with a cream-chamber and a vacuum-chamber and supports inposed between the two chambers, a perfober below, exhaust connections for the vacu-' um-chamber,a layerof material superposed on said supports and permeable by the Watery adapted to create a lower atmospheric presconstituents and impermeable by the fatty sure in the second chamber than in the first constituents of cream, substantially as dechamber, substantially as described.

scribed. In testimony whereof I have hereunto signed 5 4. Apparatus for making dairy products my name.

comprising a cream-chamber, a second chamg ber, a perforated support between the two, a CHARLES TAYLOR layer of material carried by said support and Witnesses: permeable by the watery and impermeable by WM. J. JACKSON,
